Pants-type apparel artical

Abstract

The invention provides a pants-type apparel artical, at least a central part is soft, a front waist area side is provided with required tensile strength and at least part of the front waist area (11) side is a multi-layer area (44) passing by a laminated substrate part (25) and a front waist part (26). The central part (13c) of a crotch area (13) is a single-layer area (43) only formed by a substrate part (25); the multi-layer area (44) is provided with a corner part (73) surrounded by a boundary (40), an inner edge (11d) of the front waist area (11), a junction area (60) for connecting an absorption configuration body (15) and a bottom (14) and the above concave-curve shaped side edge (19c) of the crotch area (13); and the boundary (40) of the multi-layer area (44) and the single-layer area (43) passes across the junction area (60).

Description

[0001] technical area [0002] The present invention relates to a disposable underpants type diaper, an incontinence diaper cover and other underpants type wearing articles. Background technique [0003] Conventionally, there are known wearing articles having a chassis forming the base form of the underpants-type wearing article and a liquid-absorbent structure located on the inner surface of the bottom. For example, the wearing article disclosed in Patent Document 1 has a bottom and a liquid-absorbent structure located on the inner surface of the bottom. Shaped back waist. In this wearing article, a plurality of waist elastic members extending in the lateral direction are arranged on the front waist panel and the back waist panel, and a plurality of leg parts are arranged on the extension part defining a part of the crotch region of the back waist panel. elastomer. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2005-27839 [0005] With regard to the wearing art...

AI Technical Summary

Problems solved by technology

[0006] However, when the wearing article is worn, the vicinity of the side edges of the liquid-absorbent structure extending linearly abuts against the curved thighs of the wearer, and the wearer or the assistance of the wearing assistant will help the legs While inserting into the leg openings or after inserting the legs into the leg openings, when the wearer or wearing assistant grasps both sides of the front waist region and the rear waist region and lifts up, the crotch region is located on the side of the front waist region. A part of the liquid-absorbent structure may be caught inside the thigh, and the edge of the leg opening may be stretched in the vertical direction.

In this case, the tensile stress generated at the edge of the leg opening concentrates on the portion where the shape of the edge of the leg opening greatly changes, that is, on the lower end edge of the front waist panel that extends linearly in the lateral direction. The part where the two side edges of the liquid-absorbent structure extending linearly and longitudinally intersects, and there is a possibility that a part of the wearing article may be broken from the intersecting part

In addition, when the front waist region, the rear waist region, and the crotch region are formed by separate sheet members like this wearing article, when the waist region and / or the crotch region are stretched, the front waist region and the rear waist region exist. Possibility of separating from the crotch region at the junction of the sheet members

[0007] In order to avoid this situation, although it is also considered to form the whole of the wearing article including the crotch region with a multi-layer sheet member, thereby improving the sheet strength of the bottom as a whole, in this case, it will damage the crotch region. The flexibility of the central part, and because the amount of the sheet member used increases, it leads to an increase in manufacturing cost
